Description

In the first supplement (InputData.rar), for each Ecopath model, identified with its model number in EcoBase (see Appendix C for the metadata and references of the models), one Text file provides the input data: group number (No); group name (GroupName); trophic level of the group (TrophicLevel); biomass of the group (Biomass); and matrix of the mixed trophic impact, with the impacted groups in columns and the impacting groups in rows, both identified with their group numbers. Non-living groups were removed, and mixed trophic impact values of the groups on themselves were replaced by NA.

The second supplement (Rcode.R) provides the R code used to run the Spearman rank correlation tests.
